1.e4 c6
The Caro-Kann Defence.
2.d3
Fischer avoids main lines with 2.d4 d5.
2...d5 3.Nd2 g6 4.Ngf3 Bg7 5.g3 e5 6.Bg2 Ne7 7.0-0
0-0 8.Re1 d4 9.a4 c5
This is a solid continuation; it comes to a King's
Indian type of position with reversed colours. Black has lost a
tempo with c7-c6-c5, but White's king's rook is badly placed on e1.
If it moves back to f1, White will have wasted two tempi.
Black's king's knight may not be ideally placed on e7, but it can get
to d6 via c8.
10.Nc4 Nbc6 11.c3 Be6 12.cxd4 Bxc4
Black fears what White can do on the queenside and
would like to recapture on d4 with the e-pawn.
13.dxc4 exd4
13...cxd4 comes into consideration. After the
text move the position of White's king's rook on e1 receives
justification.
14.e5
This is a useful move. White opens up a pleasing
prospect for the g2-bishop and shuts in the g7-bishop. Besides, he
threatens Ng5 followed by e6.
14...Qd7
This move prevents the aforesaid threat. It also
prepares ...Rad8 and the manoeuvre Nc6-b4 followed by ... Q-d7-f5-c2.
15.h4
15.Bf4 h6 (The threat is 16.Ng5) 16.h4 Rad8
∞ is a reasonable alternative.
15...d3
Black fears White's kingside initiative and thus tries
for immediate counterplay in the centre.
16.Bd2 Rad8 17.Bc3 Nb4 18.Nd4
White tries to introduce tactical complications.
After 18.Bxb4 cxb4 19.Qb3 Nc6 20.Rad1 Rfe8 , the e5-pawn will be
exchanged for the d3-pawn, and the position will be a draw.
18...Rfe8
This move is risky as it invites the advance e5-e6.
Black has a better continuation with 18...Nec6 19.Nxc6
(19.e6 Qe7 20.exf7+ (20.Nxc6 bxc6) 20...Qxf7 21.Ne6 Bxc3 22.bxc3 Qxf2+
23.Kh2 Nc2 with advantage to Black.; 19...bxc6
19.e6 fxe6 20.Nxe6 Bxc3 21.bxc3 Nc2 22.Nxd8 Rxd8
23.Qd2 Nxa1 24.Rxa1 Kg7 25.Re1 Ng8 (?)
It is more accurate to play 25...b6 first. Black
was afraid of 26.Bh3 . But he has a satisfactory defence with 26...Nf5
27.Bxf5 (27.Re5 Nxh4 28.gxh4 (28.Bxd7 ? 28...Nf3+) 28...Qxh3 29.Re7+
Kf8 30.Rxh7 Qg4+ 31.Kf1 Rd7 32.Qh6+ Ke8 33.Rh8+ Ke7 34.Qf8+ Ke6
35.Qe8+ White has perpetual check.; 27...Qxf5 28.Re7+ Kg8 29.Qh6
(29.Rxa7? is met by 29...Re8!) 29...Qf6 30.Qxh7+ Kf8 31.Rxa7 d2
32.Qh6+ , and White must accept perpetual check.
26.Bd5 Qxa4 27.Qxd3 Re8
Black hurries to exchange the remaining pair of rooks
to limit White's attacking chances - even at the cost of a pawn.
Its importance should not be underestimated.
Other continuations conceal danger: 27...b6?
28.Re5 (28.Qe3 Qd7 Black has sufficient defensive resources.) 28...Re8
29.Qe3 Nf6 30.Re7+ leads to disaster for Black.; 27...Qd7 28.Qe3 b6
29.h5 Qd6 30.Qg5!? and White has the initiative. - NSH
28.Rxe8 Qxe8 29.Bxb7 Nf6 (?)
29...Qe7 denying White's queen access to d6, is
better. After the retreat of the opposing bishop, Black
continues with a7-a5 and Ng8-f6; his drawing chances are considerable.
Now Black's a-pawn is held on a7.
30.Qd6 Qd7 31.Qa6 Qf7
31...Qe7 would be insufficient. After 32.Qxa7
Ng4 33.Kg2 Qf7 34.f3 Ne3+ 35.Kf2 Black is in difficulties: 35...Qe7
(35...Nxc4 36.Qxc5 and White wins.; 35...Nd1+ 36.Ke2 Nxc3+ 37.Kd3 with
excellent winning chances for White.) 36.Qa4 Ng4+ 37.fxg4 Qxb7 38.Qe8
White should have a winning position; on 38...Qb2+ comes 39.Qe2.
32.Qxa7?
After this move White loses a piece and all chances of
a win. If White manages to bring his king over to the queenside,
he has winning chances. 32.Kg2 h6 is perhaps the most exact,
Black is limited to passive defence.
a) 32...Ng4 33.Bf3 Ne5 (a)33...Nf6 fails to 34.Qd6)
34.Bd5 Qe7 35.f3 White follows with Bd5-e4 and begins to transfer his
king to the queenside; Black's situation is not enviable.;
b)32...Ne8 33.Kf1 Nf6 (b)33...Qe7? 34.Qxa7 Nd6
35.Qxc5+-) 34.Bd5 Qe7 35.f3± and Black's position is not easy.
32...Ne4! 33.f3 Nd6
Not 33...Nxg3? 34.Qxc5 Qxb7 35.Qe5+ White has winning
chances.
34.Qxc5 Nxb7 35.Qd4+
35.Qe5+ leads of course to perpetual check. But
White would like to see if Black would perhaps overstep the time
limit, for he is naturally in no danger of losing.
35...Kg8 36.Kf2 Qe7 37.Qd5+ Kf8 38.h5 gxh5
38...g5? 39.h6 gives White unnecessary
counter-chances.; 38...Nc5 39.hxg6 hxg6 40.Qd4=
39.Qxh5 Nc5 40.Qd5 Kg7 41.Qd4+ Kf7 42.Qd5+ Kg7
43.Qd4+ Kf7 44.Qd5+ ½-½
